Important: 1. New Lithium Ion batteries must be FULLY CHARGED and FULLY DISCHARGED 2 to 3 times, before being FULLY CONDITIONED. 2. The light signal may not always indicate a full charge, but the battery will be at full capacity after 3 complete charge and discharge cycles. 3. Complete charging (upon phone is turned off) and discharging will extend battery life. 4. After you go through 2 to 3 cycles, you ll never have to condition your battery again!
